I’m making an .Net Maui app where it takes photo of a plant/flower and then send it to PlantNet API and it returns a ‘scientific name’, I then compare this ‘scientific name’ into my database of plant/flowers with scientificName.

But here’s my problem – considering this code snippet, I need

string s = "Centaurea solstitialis L.";   // this is from PlantNet API
string z = "Centaurea solstitialis, C. melitensis";   // this is from my database

// this returns 'false' but I need this to return true since they're the same scientific name
Console.WriteLine("z.Contains(s): " + z.Contains(s, StringComparison.Ordinal));

I did tried to use the
s.Contains(z, StringComparison.Ordinal)

and s.Contains(z) and z.Contains(s)

but all returns false.
